ANCHOR.

SPECIFICATION forming part of Letters Patent No. 762,242, dated June 7, 1904.

I Application filed February 24, 1903. Serial No. 144,917. (No model.)

T0 ir/ZZ whom it 717,013/ concern,.-

Be it known that I, CHARLES MITCHELL, a subject of the King of Great Britain, residing at Fern Lea, Bassett, Southampton, England, have invented certain new and useful Improvements in Anchors, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in anchors for vessels; and it consists of an oscillatinghcad provided with X iiukes attached by means of a ball-and-socket connection to the shank of the anchor; and the object of my invention is to provide an anchor of the character described in the use of which the flukes will embed themselves deeply into the earth when a pull is exerted upon the cable attached to the shank; and with these and other objects in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following speciiication, of which the accompanying drawings form a part, in which the separate parts of my improve ment are designated by suitable reference characters in each of the view s, and in which- Figure l is a perspective View of my anchor. Fig. 2 is a side view showing a partin section; and Fig. 3 is a view looking down upon the fiukes, having the shank removed.

In the practice of my invention I provide a shank a having a ball formation a2 upon one end and the other end of which is enlarged and flattened and provided with an eye a3, in which the cable is secured.

To the ball a2 or' the shank a I attach a member composed of an annular member having iukes o2 and a socket-piece whichis secured to the annular member by means of screws 53, and the said member is free to turn on the ball 0,2 of the shank a, the connection of these points constituting an ordinaryball-and-sockct joint. Between the linkes Z22 the annular member is provided with webs b4, and upon one or more of these iiukes I form the eye c, which is designed to afford a means for attaching a buoy-rope to said turnable member.

In operation when the anchor reaches the earth the Webs between the iiukes will penetrate the surface and when a pull is exerted upon the anchor through the attached cable will act as a fulcrum and cause the flukes to be driven farther into the earth, and the member composed of the parts and I) will turn upon the ball a2 of the shank a.

In the drawingsI have shown a rigid shank composed of one piece; but, if desired, I may make the shank of two pieces joined at the center, so that the sections will fold together.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

An anchor of the character described, composed of a shank having a ball formation at one end, an oscillating or turnable head mounted thereon and composed of an annular piece L and a socket-piece a* secured to said annular piece, said annular piece being provided with flukes and with webs If, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

CHARLES MITCHELL.
